Finally we can present our T-RING prototype!
In the new T-PAPER video you can see one of the final applications which could be realized with paper-based piezoelectric loudspeakers. A 360° surround-sound installation can be used in exhibition booth as well as for acoustic accompaniment of museum exhibits.
T-PAPER team published their new scientific paper on „Paper-Embedded Roll-to-Roll Mass Printed Piezoelectric Transducers“ in Advanced Materials. Georg C. Schmidt and co-authors could realize an innovative concept for large-area piezoelectric devices on paper made by means of cost efficient roll-to-roll mass printing. Also post printing technologies including inline poling were realized at the Institute for Print and Media Technology.
TU Chemnitz presented in the press release a 360° surround-sound installation made with a 387 cm long paper web consisting of 56 piezoelectric speakers. The paper loudspeaker web including printed wiring weighs only about 150 gramm.
Video clip on T-PAPER project is available on the Youtube channel of TU Chemnitz.
